Abstract: A truck body includes a rigid aluminum frame, the frame comprising: a load floor and underbody comprising structural extrusions oriented longitudinally; subassemblies comprising aluminum extrusions formed into frames defining the body walls; and, at least one subassembly comprising aluminum extrusions formed into a frame defining the body roof, and wherein the load floor, wall subassemblies, and roof subassembly are fastened together to form a rigid final assembly. Roll formed steel tubular members may be substituted for the aluminum extrusions. The invention may further be adapted to make modular trailers that can be customized by choosing among different wall and roof modules. Related assembly methods are also disclosed.

Abstract: Embodiments may include a traction system, for example a cervical traction system for a neck of a user. Systems may include a housing assembly, plate assembly, handle assembly, and cable assembly. The housing assembly may include a drive assembly. The plate assembly may be operatively connected to the drive assembly. The handle assembly may be operatively connected to the drive assembly. The handle assembly may be configured to actuate movement of the plate assembly relative to the housing assembly. Embodiments may be configured to apply traction to the neck thereby providing a distraction distance or force to a portion of the cervical spine.

Abstract: An improvement in a process for the press fit assembly of two parts having an interference fit, wherein one of the two parts is provided with a grooved surface. A pre-applied dry to-the-touch sealant, adapted to be cured upon assembly of the two parts, is applied on the grooves prior to assembly.
